Director Zack Snyder has been filming Batman V. Superman: Dawn of Justice in Michigan for a large part of the summer, so many might expect filming to wrap up fairly soon. However, MLive uncovered a mysterious new casting call, which indicates the film will still be shooting in mid-October.

The casting call appears on two different websites, and one of the websites notes the work is for Batman v. Superman: Dawn of Justice, while the other casting call doesn't indicate the film's name.

The casting calls are for all night shoots in Lansing, Michigan that will take place on October 16th and 17th, 2014. The scene calls for background actors that are least 18 years of age.

For an all night shoot, it must be a fairly significant scene. Could it be for the final battle or conflict in the film? Or is it for Batman V. Superman: Dawn of Justice at all? There have been lots of rumors that Justice League is filming back-to-back with Batman V. Superman: Dawn of Justice, so it's always possible this two-night shoot could be the first scene in a Justice League movie.

Batman V. Superman:Dawn of Justice is scheduled to be released in movie theaters on March 25, 2016.
